LOUIS EVAREST BARBEAU, OF LONDON, ENGLAND.

DEVICE FOR TURNING BAGS.

SPECIFICATION forming part of Letters Patent No. 503,692, dated August22, 1893.

Application filed October 19. 1892. Serial N0.449,321- (Ito model.)

To all whom it may concern:

Be it known that I, LOUIS EVAREST BAR- BEAU, a subject of the Queen ofGreat Britain, residing at London, England, have invented new and usefulImprovements in Devices for Turning Bags, of which the following is aspecification.

This invention relates to a device which is designed for use in bagfactories for turning bags in the course of manufacture and also inflour mills, malt houses and other establishments where bags arerequired to be turned for cleaning them.

My invention has for its object to provide a simple and inexpensivecontrivance whereby the bags or sacks can be turned more rapidly than bythe use of the hands alone.

In the accompanying drawings consisting of two sheets :Figure 1 is afront elevation of my improved bag turning device. Fig. 2 is a rear viewthereof, showing a sack in position thereon preparatory to being turnedthe sack being shown in section. Fig. 3 is a side elevation of thedevice with thebag shown in section. Fig. 4 is a top plan view thereof.Fig. 5 is an enlarged sectional elevation of the upper part of one ofthe standards, showing the anti-friction balls applied thereto and oneof the caps which confine the balls removed. Fig. 6 is alongitudinalsection in line w--w, Fig. 5, with both caps in place. Fig. 7 is a sideelevation of a modified form of the device. Fig. 8 is a similar view ofanother modification. Fig. 9 is a sectional elevation of the upper partof one of the standards, Fig. 8, showing anti-friction rollers appliedto the same and one of the caps which confine the rollers removed. Fig.10 is a top plan view thereof with both caps in place.

Likeletters of reference refer to like parts in the several views.

In Figs. 1 to 6, inclusive, A represents abase plate secured to thefloor or other support, or made sufficiently heavy to support the devicewithout fastenings, and B B are upright bars or standards pivoted attheir lower ends to upwardly projecting lugs or ears a formed on thebase plate. These standards cross each other, and are adj ustablyconnected together, where they intersect, by a transverse clamping bolt0 passing through slots d formed lengthwise in the standards and havinga thumb nut 0. Upon loosening the thu mb nut, the clamping bolt may beraised or lowered in the slots of the standards so as to separate theirupper ends to a greater or less extent.

eis a spiral spring connecting the standards between their lower endsand the clamping boltc and tending to spread the upper ends of thestandards apart upon loosening the clamping bolt. The upper end of eachstandard is preferably provided with anti-friction balls or rollers. Inthe construction represented in Figs. 1 to 6, each staudardis providedwith a row of anti-friction balls f which extend from the top of thestandard to the outer side thereof. These balls are arranged in groovesformed in the adjacent sides of two cap pieces G secured to the upperend of the standard by a transverse bolt 9, as shown in Figs. 5 and 6.The ball grooves are so formed as to confine the balls therein'and atthe same time allow them to revolve freely.

In the use of my improved device, the upper edge of the sack is firstturned outwardly around the entire month of the sack to the depth ofabout two inches. This turned-over portion is then seized on oppositesides of the sack, placed upon the upper ends of the standards and thendrawn downward over the same until the bottom of the sack rests upon theupper ends of the standards, whereby the sack is reversed or turnedinside out. The halls f reduce the friction of the sack against thestandards and facilitate the operation of turning. As the bag is drawnover these balls, those nearest the outer side of each standard willturn about a horizontal axis, substantially at right angles to the planeof the two standards, while those nearest the crown of each standardwill turn about a horizontal axis substantially in the plane of bothstandards, as represented by the arrows in Fig. 5, which directions ofrotation correspond with and are produced by the different directions inwhich the bag moves over each standard at different portions of its top.

By making the standards adjustable upon each other, as before described,they can be set at different distances apart to suit sacks of varioussizes.

Instead of crossing the two standards of the sack-turner, they may beseparated and conis drawn over them.

2 v scarce nected by an adjustable brace Hwhich is secured to thesestandards by transverse clamping bolts passing through longitudinalslots in the standards, as shown in Fig.7. In this modification thestandards are inclined or' made to diverge upwar ly, S0 that uponadjusting the. brace H up or down,zthel-standf ards are contracted orspread apart.-

In the modification shown vin Fig.8, the standards are connected by anadj ustable brace, as in the construction shown in Fig. 7, but theirlower ends are pivoted toindependent lugs instead of to a single lug, asin Fig.7.?

I In lieu of the balls f, anti-frictionrollersf'i may be employed, asshown in Figs. 8 and9.

In this case the axis of. the .outer roller of: each standardis arrangedat. rightangles: to;

thevplane of the standards and theaxes ofthe inner rollers ina parallelplane therevvithpas.

shown, whereby substantially the same move-Q ment is produced in theserollers which takes" place in the anti-friction balls when thebag Theseballs .or roller-s are,- =however, not indispensable and may. be

omitted, ifdesired, and theupper ends-or heads of the standards. mayberounded, seats to present asmooth bearing surface to the sack.

My improved, sack turner forms a very use,

ful accessoryto. bag ifactories,. flourmills-and other establishments inwhich a. large number of bags have to be turned, as it enables amuch"greatennumberv to be turned in-a given time than byitheoldmethod-of usingonly the hands.
